EDWARD (J. WHITLEY AND EDWARD L. KNOWLTON, OF WILLIAMSTOWN, VIEST VIRGINIA.

GLASS-BLOWER.

Application filed October 26, 1918.

To all whom it may concern:

lie it known that we, EDWARD 0. VIII!- LE) and ED\VA1{D L. KNowL'roN, citizens of the United States, residing at VVilliamstown, in the county of Wood and State of West Virginia, have invented certain new and useful Improvements in Glass-Blowers, of which the following is a specification.

Our invention relates to apparatus for producing blown glass tumblers or other articles of glass-ware.

An important object of the invention is to provide apparatus of the above mentioned character, so constructed that a plurality of tumblers or the like may be drawn and blown at the same operation, thereby greatly reducing the cost of their production.

A further object of the invention is to provide apparatus of the above mentioned character, which is convenient to operate and simple in construction.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of apparatus embodying our invention,

Fig. 2 is an edge elevation of the same,

Fig. 3 is a horizontal sectional View taken on line 33 of Fig. 2,

Fig. i is an enlarged detail section through the connection between the glass take-up nozzle and the air supply pipe, and,

Fig. 5 is a side elevation of a slightly different form of apparatus.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of our invention, the numeral 10 designates a plurality of pipes, arranged in parallel relation, and constituting the body portion of the apparatus. These pipes, at their rear ends, are bent into curved sections 11, connected at their upper ends with a com mon coupling 12, having connection with a mouth tube 13. At their lower ends, the pipes 10 are connected by a transverse member 11. The lower ends of the pipes 10 are bent horizontally, forming horizontal sections 15, carrying forwardly projecting sections 16, which are spaced a substantial distance and are arranged in parallel relation. The sections 16 and 15 form a U-shaped Specification of Letters Patent.

member. The pipe sections 16 are connected by a transverse bar 17.

The numeral 18 designates glass take-up nozzles, which are preferably tapered and decrease in diameter rearwardly. The nozzles 18 are carried by tubular stems 19. Each tubular stem 19, as more clearly shown in Fig. *1, is provided with a gear 20, rigidly secured thereto and preferably formed integral therewith. The gear has a flange 20 for a purpose to be described. The tubular spindle 19 has a tubular extension 21 projectmg beyond the gear 20, and rotatably held within the pipe section 16. A stuffing box 24;, is provided, having screw-threaded engagement with the lower end of the pipe section 16, as shown at 25, and receiving packing 26, to prevent any leakage of air between the extension 21 and the pipe section 16.

Arranged between the two gears 20 is a larger gear 27 engaging the same, as shown. The gear 27 is rigidly secured to a rotatable shaft 28, journaled through openings formed in the bars 14 and 17. This shaft 28 is arranged between the parallel pipes 10, as shown. The longitudinal movement or displacement of the shaft 28 is prevented by means of rings 29 rigidly secured thereto and arranged upon opposite sides of the bar 17. To the upper end of the shaft 28 is rigidly secured a handle 30, arranged within the space formed by the curved pipe sections 11, as shown. The larger gear 27 also engages with the flanges, which prevents the forward displacement of the tubular spindles 19.

In Fig. 5, we have shown a slightly different form of apparatus. In this second form of apparatus, we provide a gear 31, corresponding to the gear 27 but smaller. The gear 31 is rigidly secured to the shaft 28. The gear 31 engages intermediate gears 32, rigidly secured to spindles 33 journaled through openings in the bar 17. The gears 32 engage the gears 20, as shown. i ll other parts of the apparatus remain identical to those described in connection with the first form of the apparatus.

In the use of the apparatus, in n'oducing blown tumblers, the nozzles 18 are dipped into the heated or molten glass, and turned therein upon their longitudinal axes, by a turning movement of the handle 30. When a suificient amount of glass is collected by the nozzles 18, they are withdrawn from the molten mass of glass and the glass adhering to the nozzles is shaped by turning the nozzles upon their longitudinal axes 18 while the glass contacts with a flat slab of marble, this turning movement being effected by a. turning of the handle 30. After this operation, the nozzles are inserted Within the molds, corresponding in arrangement and number to the nozzles, and the tube 13 inserted in the operators mouth, who blows through the same. The air passes through the various pipe sections into the tubular spindles 19 and through the nozzles 18. The nozzles may be suitably turned upon their longitudinal axes, during this blowing operation, by a turning movement of the handle 30. It is obvious that the tumble-rs will be properly blown and shaped by this operation.

lVhile we have shown and described the apparatus as embodying two nozzles 18, it is obvious that this number may be in creased, as may be found advantageous,

It is to be understood that the forms of our invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described our invention, We claim:

1. In apparatus of the character described, the combination with a plurality of pipes arranged in approximately parallel relation and bent at their forward ends to provide laterally extending portions having a recess upon one side thereof, of a mouth tube connected with the forward ends of the laterally bent portions of the pipes, a plurality of nozzles having tubular extensions rotatably mounted within the forward ends of the pipes, a corresponding number of gears carried by the tubular spindles to turn them, a gear arranged between the plurality of gears to drive them, a driving shaft connected with the said gear and extending longitudinally of and between the pipes and connected therewith, and a handle connected with the rear end of the shaft and arranged for operation within the said recess.

2. In apparatus of the character described, the combination with a plurality of pipes arranged in approximately parallel relation and spaced laterally, means for introducing air under pressure into the rear ends of the pipes, a plurality of nozzles having tubular extensions rotatably mounted within the for ward ends of the pipes, gears carried by the tubular extensions to turn the nozzles, said gears being provided with flanges, a transverse support connecting the pipes, a shaft connected with the transverse support to turn with relation thereto and capable of moving longitudinally with relation thereto, a common gear secured to the shaft to rotate therewith and engaging the first named gears to drive them and contacting with the flanges of the first named gears to prevent the tubular extensions from being withdrawn from the pipes, means to turn the shaft.

In testimony whereof we afiix our signatures in presence of two witnesses.
